What we do

WattTime is a nonprofit that enables smart devices to automatically sync the times they use power to moments of clean sustainable electricity. How clean is your power grid? The answer changes every 5 minutes.

How it works

WattTime's analysis combines real-time data from power grid operators, the EPA, and more. We detect moments when using electricity will use a cleaner, more environmentally friendly power plant than normal. Why not use energy then?

Who uses it

WattTime’s software is now incorporated on select smart thermostats, commercial building HVAC systems, and more. The “WattTime-enabled” logo means a company has chosen to give you the power to go green. Look for this logo on more equipment types as we grow!
